Title: Pattern forming material
Inventor: TODA KAZUO
IPC: G03F7/26
Filed: 1982-04-23
Abstract: PURPOSE:To obtain a pattern forming material of positive type having sufficient sensitivity to radiant rays such as electron beams, and high resistance to plasma etching, by using a material consisting of polybenzyl methacrylate and an org. polymer soluble in alkaline chemicals. CONSTITUTION:Polydimethylbenzyl methacrylate produces carboxylic acid on irradiation of electron beams and the use of it as an inhibitor provides a useful positive resist having sensitivity to electron beams. Addition of 5-10wt% polydimethylbenzyl methacrylate to polyhydroxystyrene insolubilizes this mixture in alkaline solns. The following electron beam irradiation decomposes polydimethylbenzyl methacrylate that has hindered dissolution of polyhydroxystyrene in the alkaline solns., and produces carboxylic acid, and remarkably raises its alkali solubility, resulting in selective solubilization of the irradiated parts in alkali and permitting pattern formation.

Title: Refining furnace providing tapping hole
Inventor: MURAKI YASUNORI
IPC: C21C5/46
Filed: 1987-03-25
Abstract: PURPOSE:To prevent flow-out of slag into a ladle caused by vortex even in case molten metal in a furnace is decreased, to eliminate necessity of rise of the molten metal temp. in the refining furnace and to improve the product yield by forming the furnace wall around a molten metal tapping hole into funnel shape. CONSTITUTION:By forming projecting part 10 of the furnace wall around the molten metal tapping hole 6 in the refining furnace of converter 1, etc., into the funnel shape, at the time of flowing out the molten metal 4 into the ladle from the tapping hole 6 by tilting of the converter 1 at finishing of the blowing, the height from the molten metal surface to the tapping hole 6 can be held to high position. Therefore, even in case the molten metal 4 is reduced and slag 5 is reached to the inner wall part of refractory 3, the vortex can not be developed just at upper zone of the tapping hole 6. In this case, as the molten metal 4 is remained at the above upper zone by plugging the tapping hole 6 as remaining the molten steel 4, the flow-out of the slag 5 can be extremely reduced. Therefore, the slag removal in the ladle is not necessary and also rise of the molten metal temp. in the converter 1 is not necessary, and the product yield can be improved.

IPC: H01F27/24
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To suppress a temperature increase without increasing cost remarkably by using one of a pair of cores as a core with less core less than the other. SOLUTION: Two U-shaped cores 14 and 15 form a square-shaped core by joining the edge parts of leg parts 14a and 14b and leg parts 15a and 15b, respectively, via gap spacers 11a and 11b in specific directions for preventing the saturation decrease of the cores 14 and 15. In this case, in a transformer device 13, the core loss is allowed to differ between the cores 14 and 15. More specifically, the core 15 located at a lower side is constituted of a low-loss material made of Mn-Zn ferrite, while the core 14 located at an upper side is constituted of a general-purpose material made of Mn-Zn ferrite, thus extremely suppressing a temperature increase.

Filed: 1986-03-27
Abstract: PURPOSE:To accurately detect the scratch of the surfaces of an Al strip in an annealing furnace when the strip is annealed by heating in the furnace during continuous conveyance in a floating state, by electrically insulating the strip from the members of the furnace and keeping the strip at positive potential so as to electrically detect the contact of the strip with parts in the furnace. CONSTITUTION:An Al strip 1 uncoiled from an uncoiling roll 4 enters an annealing furnace 2 through bridle rolls 5 and a tension roll 6. In the furnace 2, the strip 1 is annealed with hot air blown from nozzles 3 and the annealed strip 1 is taken out of the furnace 2 and coiled around a roll 7. The strip 1 is electrically insulated from the rolls 4, 5, 6, 7 and passed through the furnace 2 in a floating state with the tension rolls 6, 6. When the strip 1 comes in contact with parts in the furnace 2 from some cause, electric current flows in the strip 1 kept at positive potential in an insulated state, so the contact can be immediately detected with a buzzer or a lamp 11.

Abstract: PURPOSE:To improve and stabilize the quality of single crystal by optically measuring the level of the molten raw material at the seeding and during the pull-up operation and suppressing the fluctuation of the molten liquid level during the operation. CONSTITUTION:The level gauge of a single crystal pull-up apparatus having a cylindrical heat-shielding member enclosing a single crystal is provided with two light sources 11, 12 and a light-receiving element 13 receiving the light reflected from the molten liquid surface. Laser beams radiated from the light sources are passed through the gap between the single crystal 4 pulled up from the molten raw material 3 in a crucible 1 and the heat-shielding member 5 surrounding the single crystal and radiated to the molten liquid surface around the single crystal 4. The molten liquid surface irradiated with the beam has flat form at the seeding stage and curved form during the pull-up operation. The level of the flat molten liquid surface at the seeding stage is measured by the light source 11 and the receiving element 13 (the 2nd measuring system). When pull-up operation is started, the light source is switched from 11 to 12 and the level of the curved molten liquid surface is measured by the light source 12 and the receiving element 13 (the 1st measuring system). The 1st measuring system is initialized based on the level measured by the 2nd measuring system.
